Critical race theory is about learning what actually happened to different groups of people to create the society we live in right now, not about segregating them today. If you don't learn from history, you're doomed to repeat it.

That argument does have nothing at all to do with the content of critical race theory...which is pretty much exactly like most arguments I’ve seen “against” it recently. Probably has something to do with all the right-wing rage mongering about that term being attached to things that have nothing to do with CRT, and about keeping teaching it out of domains where no one is even interested in putting it.
